BAG-SHAKING MACHINE.

Application filed November 4, 1914.

To (all whom it may concern:

Be it known that I, LOUIS P. WILLSEA, a citizen of the United States, residing at Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Bag-Shaking Machines, of which the following is a specification.

The object of this invention is to provide a machine for cleaning bags such as have been used for holding cement, plaster, etc.

This and other objects of the invention will be fully illustrated in the drawings, described in the specification and pointed out in the claims at the end thereof.

In the drawings, Figure 1 is a top plan view of my improved machine. Fig. 2 is a side elevation of the machine. Fig. 3 is a vertical section on the line 3 -3 of Fig. 1. Fig. 4 is a vertical section on the line 1 1 of Fig. 6, showing the driving and counting'mechanism. Fig. 5 is a hori- Zontal section on the line 5 '5 of Fig. 4:. Fig. 6 is a plan view of a part of the top of the machine with the cover removed. Fig. 7 is a detail view of the mechanism for operating the bell. Fig. 8 is a detail view of the device for locking the driving mechanism. Fig. 9 is a vertical section taken on the line 9*9* of Fig. 8. Fig. 10 is a horizontal section taken on the line 1O"1O of Fig. 9.

In the drawings, like reference numerals indicate like parts.

In the drawings 1 indicates the hollow base of the machine which preferably is square as shown in Fig. 1 and one side of which is open, it being closed by a vertically sliding door 2. The top portion of this base is a plate 3 having a circular opening therein surrounded by a circular flange 4. on which rests the cylindrical body 5 to which it is securely fastened by the bolts 6, 7 and 8, which bolts engage with lugs in the ring 9 and in the plate 3 so that by drawing these parts together by the bolts the cylindrical body is clamped in place. Mounted transversely of the base 1 are the rock shafts 10 and 11, on the outer end of which are keyed the cranks 12 and 13 by which the shafts may be rocked. Mounted at the side of the machine is the eccentric rod 1 1- whi'ch carries a stirrup on the bottom thereof which engages with the cranks 12 Specification of Letters Patent.

and 13 so that upon the vertical reciprocation of the rod 14:, the cranks 12 and 13 and the shafts 10 and '10 connected thereto are rocked. On the top of the eccentric rod 14 is an eccentric strap 15 which engages with an eccentric 16 mounted to rotate on the shaft 17. Keyed to the eccentric 16 is the pinion 18 which also rotates around the shaft 17. Meshing with the pinion 18 is the gear 19 which revolves with the shaft 20, which shaft is mounted to rotate in the bearings provided therefor on the front and back of the casing 21, which casing is formed preferably integral with the ring 9. The cover plate 22 of the casing is made detachable and is held in place by suitable bolts. The bottom of the casing is slotted at 23 to receive the eccentric rod and parts connected thereto and give them room for movement.

On the outer end of the shaft is provided the male member 24 of the clutch, which member has a splined engagement with the shaft. Loosely mounted to rotate on the shaft is the pulley 25, having the female member of clutch therein with which the male member of the clutch is adapted to engage for the purpose of rotating the shaft 20. The male member of the clutch is operated by the lever 26. Keyed to or integral with the pulley 25 is the fly wheel 27.

The clutch, pulley and fly wheel may be omitted and instead the hand wheel 28 may be used, having a handle 29 thereon. This hand wheel is big enough to operate as a fly wheel and by it the machine may be driven, by either the pulley or hand wheel the shaft 20 is rotated and with it the gear 19, which meshes with and drives the pinion 18, driving the eccentric and parts connected therewith.

Inside the cylindrical casing 5 are mounted the heaters 30 and 31, by which the bags are beaten. from the shafts 10 and 11 as follows: Keyed to the shafts arethe frames 32 and 33 each of which has two cranks thereon connected by a yoke. These cranks. are perforated at the ends so as to receive the ends of the heaters, which ends are inserted and clamped therein by means of the set screws 32 and 33 shown, the whole being arranged so that by the rotation of the eccentric 16 a recipro- These heaters are supported cation is given to the eccentric rod 14 and a slight oscillation is communicated thereby to the cranks 12 and 13, the frames 32 and 33 and the heaters 30 and 31.

In operation the heaters are first brought together, as shown in Fig. 3, and the bag is inverted over them,as shown by dotted lines in Fig. 3. The machine is then set in motion causing the heaters to vibrate which will cause the bag to be beaten and shaken and the dust to be expelled therefrom. So that the heaters 30 and 31 will not interfere with each other, one of them is made a little narrow at the top and a little shorter than the other beater so that the short beater will nest in the long heater and will not strike it when they come together.

For the purpose of holding the bag in place on the heaters and for the purpose of counting the number of bags that are beaten by the machine, I provide the mechanism which I will now describe. Keyed to the shaft 20 or integral with the gear 19 are the cams 34- and 35, the cam 34 having three elevations thereon, each of which is intended to operate the latch 36 and the cam 35 has one elevation thereon and is intended to operate the latch 37. On top of the casing 21 is the stud 38 on which is pivotally mounted the hub 39 carrying the guard 40 thereon. Integral with the hub 39 is the lug 41 to which is attached the spring 42, the other end of which is connected to the lug 43 on the easing 21. Integral with the hub 39 is the lug 44 with which the latch 37 engages for the purpose of holding the guard 40 in the position shown in full lines in Fig. 5, and while in this position the heaters are drawn together so that a sack can be placed thereon. When the shaft 20 is rotated the cam 35 raises the latch 37 at its lower end and draws it down at the upper end and away from the ing 44. This releases the guard 40 which is drawn from the full line position to the dotted line position, shown in Fig. 5, by the contraction of the spring 42. A stop 45 is provided against which it is held in correct position over the middle of the bag. WVhile in this position the upper end of the latch 36 can engage between the lugs on the hub 39, by which the guard 40 is carried, this latch being normally pressed up into engagement withthe hub by means of a spring 46 and the parts are so related that when the heaters are spread apart, as shown in full line position by Fig. 3, the depressions on the cam 34 permit the latch 36 to remain in engagement with the pair of lugs on the hub 39 so that the machine at the end of its operation must be stopped with one of the elevations of the cam 34 in engagement with the latch 36, holding it out of engagement with the guard 40, permitting the guard 40 to be drawn to the full line position in Fig. 5, upon which the latch 37 will engage it and hold it in full line position, the lower end of the latch 37 being weighted so as to cause the upper end to rise and engage with the lug 44.

For the purpose of counting the oscillations of the guard 40 and the number of bags cleaned by the machine, I provide the following mechanism. Mounted on the stud 38 is a ratchet wheel 4-7 having fifty teeth thereon, which ratchet wheel is held against backward rotation by the pawl 48 which is pivotally mounted on the casing 41 and is held in engagement with the ratchet wheel by the spring 49. Mounted to oscillate on the stud 38 is the lever 51, having a pawl 52 thereon, which is held in engagement with the ratchet wheel by a spring 53. On the casing 21 is provided the lug 54 which limits the backward movement of the lever 51. A coil spring 55 is provided on the stud 33, the free end of which engages with the pin 56 on the lever 51, by which spring the lever 51 is held in its retracted position. The lever 51 is engaged by the guard 40 as the guard moves from dotted position to the full line position, shown in Fig. 5, the guard engaging with the downwardly extending end, shown in Fig. 4, by which engagement the lever is carried with the guard through about eight or ten degrees from the full line position in Fig. 6 to the dotted line position of the lever in Fig. 5, the movement of the lever being suflicient to advance the ratchet wheel 47 one tooth but not enough to advance it two teeth. As the guard moves to the dotted line position, shown in Fig. 5, the lever 51 is retracted by the spring 55 to the full line position, shown in Fig. 6 and in moving to this position the lever 51 engages with the crank 57 through which it drives a counter 58, which counts the number of oscillations of the guard. Integral with the ratchet wheel 47 is the cam 59, having a single depression therein. Pivotally mounted on the casing at the side of this cam is the crank 60 having one arm thereof engaging with the top surface of the cam and the other arm oh"- set therefrom is provided with a hammer 61 which drops to strike the bell 62 when the inner end of the crank is released by the depression of the cam 59, the hammer being accelerated in the striking movement by the spring 63. As the ratchet wheel 47 has fifty teeth thereon and is driven forward a single tooth for each oscillation of the guard 40, it will make a complete revolution when the guard has made fifty oscillations, indicating that fifty bags have been cleaned and the ringing of the bell also indicates that fifty bags have been cleaned. It will also be understood that any other number of teeth may be provided on the ratchet wheel instead.

For the purpose of holding the machine against operation, the locking pin 64 is provided as shown in Fig. 8, which pin is normally pressed upward by the spring 65 into engagement with the teeth of the pinion 18 preventing the turning of the pinion and to release the pin, the pin 6st is pulled down and given a quarter turn. The pin 64: carries a small pin which passes into a socket on the lug 66 and which engages with the lower surface of the lug when the pin is drawn down and given a quarter turn for the purpose of holding the pin out of engagement from the pinion.

For the purpose of preventing the escape of dust and even collecting and saving it, the base 1 may be connected to a fan so that the air will be drawn downwardly through the cylindrical casing 5 and out of the base 1. For this purpose an opening 70 is pro vided in the base.

The operation of my machine is as follows: The machine is stopped with the heaters drawn together at the top and the bag is then inverted over the heaters as shown in dotted lines in Fig. 3. The machine is then started and the guard 40 swings from the full line position to the dotted line position, as shown in Fig. 5, holding the bag on the heater. As the machine operates the heaters oscillate and beat the bags, knocking and shaking the dust from them, which dust falls down in the base of the machine and may be drawn down by the air current through the opening 70 in the base of the machine. After the shaking of the bag is completed the machine is stopped with the heaters drawn together. The guard 40 is then drawn aside to the full line position in Fig. 5, in which position it is locked by the latch 87. The clean hag may be drawn out and another bag put in its place, after which the above cycle of operations will be repeated, the guard a0 being released from the full line position, shown in Fig. 5, on the first rotation of the cam 45. With each operation of the guard 40 the ratchet wheel l? will be operated a single tooth and when the ratchet wheel has made a complete revolution the bell will ring, indicating that the guard has heenoperated fifty times and that fifty bags have been cleaned by the machine.
